Gabrielle Venora Petito (March 19, 1999 – August 27(?), 2021) was an American woman whose disappearance was the subject of much speculation and coverage in the news media and on social media. Her family lost contact with her in late August 2021 while she was on a vanlife trip across the United States with her fiancé, Brian Laundrie.
The return of Laundrie to his home in Florida in their white camper van without Petito on September 1, and his refusal to comment about her whereabouts, led to concerns about her well-being. After intense speculation and activity in social media channels, on September 19, 2021, human remains consistent with Petito's description were found in Bridger–Teton National Forest in Wyoming. An autopsy on September 21 confirmed it was Petito with a preliminary determination that the manner of death was a homicide. Authorities are in a search for Laundrie who has been missing since September 14(?).
